Notice that for $\theta = , 40,$ and $80$ degrees you have $\tan^2(3\theta) = 3$ The tangent triple angle formula, which you can get from the tangent angle addition formula, says that $$\tan(3\theta) = {3\tan(\theta) \tan^3(\theta) \over 1 3 \tan^2(\theta)}$$ So the equation $\tan^2(3\theta) = 3$ can be expressed as $$(3\tan(\theta) \tan^3(\theta))^2 = 3(1 3 Evaluate (i) tan{2 tan^1 (1/5) (π/4)} (ii) tan{(1/2) cos^1 (√5/3) asked in Inverse Trigonometric Functions by Aryan01 ( 501k points) inverse trigonometric functions Transcript Example 14 Show that tan 3 tan 2 tan = tan 3 tan 2 tan We know that 3 = 2 Therefe, tan 3 = tan (2 ) tan 3 = tan 2 tan 1 tan 2 tan tan 3 tan 3 tan 2

We know that sin 2 (x)/cos 2 (x)= tan 2 (x), and cos 2 (x)/cos 2 (x) = 1 So the equation (i) after substituting becomes tan 2 (x) 1= 1/cos 2 (x) ——– (ii) Now we know that 1/cos 2 (x)= sec 2 (x) So on substitution equation (ii) becomes tan 2 (x) 1= sec 2 (x)Tan2 (x) = 1 3 tan 2 ( x) = 1 3 Take the square square root of both sides of the equation equation to eliminate the exponent on the left side tan(x) = ±√1 3 tan ( x) = ± 1 3 The complete solution is the result of both the positive and negative portions of the solution Tap for more steps The Second Derivative Of tan^2x To calculate the second derivative of a function, differentiate the first derivative From above, we found that the first derivative of tan^2x = 2tan(x)sec 2 (x) So to find the second derivative of tan^2x, we need to differentiate 2tan(x)sec 2 (x) We can use the product and chain rules, and then simplify to find the derivative of
